ATTACHMENT FOR TELEPHONES.

Application filed April 30, 1923. Serial No. 635,734.

This invention relates to attachments for telephone instruments.

An object of the present invention is the provision of means whereby a radio receiving apparatus may be coupled or connected with a telephone, so that the sounds received through the apparatus may be transmitted over the telephone wires.

Another object of the invention is the provision of an attachment of this character which will permit the use of the telephone without disconnecting the radio apparatus.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings 2( Figure 1 is an elevation of the invention shown applied.

Figure 2 is an enlarged view of the same.

Figure 3 is a section on the line 33 of Figure 2.

Figure 4- is an elevation showing a modilied form of the invention.

Figure 5 is a section on the line 5-5 of Figure 4.

Figure 6 is an elevation of a still further modified form of the invention.

Figure 7 is a section on the line 7-7 of Figure 6.

Referring to the drawings in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a telephone instrument, the transmitter of which is indicated at 11.

The invention which is designed for the purpose of coupling a radio receiving apparatus to the telephone instrument embodies a coupling member 12 which is of hollow construction and is substantially Y shaped in configuration. The member 12 includes a chamber 13 from which extend oppositely disposed passages 14 which are open at their outer ends. These passages extend from one end or the chamber 13 and the opposite end of the said chamber is open and is exteriorly threaded as shown at 15 for removable engagement with the transmitter 11, after the usual mouth piece has been removed.

The outer open ends of the passage 14 are adapted for connection with the head phones 16 of a radio receiving apparatus shown in diagram at R, the usual conductor lit 17 extending from these phones to said apparatus. To accomplish this, each oi? the arms within which the passages 14 are located, are provided with straps 18 whose free ends are adapted. for adjustable connection with catches or similar securing devices 19. The head phones 16 will thus be securely held in position for communication with the passages 14. Washers or cushioning rings 20 surround the outer ends of the passages 14 and act to provide a ti ht joint between the passages and phones, so as to prevent the escape of sound.

If desired; the coupling member 12 may be provided with an opening which is closed by a removable closure 21, spring fingers 22 extending from each end of the closure for engagement within the coupling member so as to hold the said closure in place.

In Figures 4 and 5 of the drawings the coupling member shown is adapted for use with a single head piece. In this form of the invention the said member includes a threaded section 23 which may be removably secured to a telephone transmitter 11 and a section 24 which is adapted to have attached thereto a single head phone 16, the attaching means being the same as that previously described. The section 23 is provided with an outwardly flared mouth 25 which frictionally receives the section 24 so that the latter may be conveniently removed when it is desired to use the telephone in the ordinary manner.

In Figures 6 and 7 the form of the invention shown is substantially the same as that shown in Figures 4 and 5 except that the section 24' oi the coupling member has an interiorly threaded mouth 26 which is adapted for removable connection with a loud speaker receiver 27 which may be connected to a radio receiving apparatus.

It will be apparent from the foregoing description and accompanying drawings that the invention provides means whereby a radio receiving apparatus may be conveniently connected to a telephone instrument and the sounds received through the apparatus will be transmitted over the telephone wires to any desired point or telephone station.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is As an article of manufacture, a connector for radio ear phones and a telephone transmitter, consisting of a hollow body provided with a central chamber substantially midway the ends of the body, said body terminating at one end in a single tubular extension er;- teriorly threaded for connecting into a threaded socket oi' the transmitter, said body at its other end'terminating in branch tubular extensions extending divergently provided with cushioning rings fitted onto and into the ends of the branch extensions, and with which the ear phones of a radio receiv ing apparatus are adapted to engage, ad-

justable means for removably holding the ear phones in engaged position, said chamher being enlarged and constituting a sound compartment and communicating with the passages through the single and branch tubular extensions.

In testimony whereof I ailix my signature.
